What is an Industrial Defense™ Speedstack7 ™ lens protector?

SpeedStack7™ is Industrial Defense™'s professional-grade 7-layer tear-off lens protection system. Designed for industrial respirators, sandblasting hoods, and protective headgear, SpeedStack7™ lets you restore clear vision instantly—simply tear off the soiled layer and get back to work in seconds.

How does the 7-layer tear-off system work?

Each SpeedStack7™ application provides 7 protective layers stacked together. When your top layer gets covered in overspray, dust, or debris, simply grip the tear-off tab and pull—the soiled layer peels away instantly, revealing a fresh, optically-clear surface underneath. Tear. Clear. Continue.™

What makes SpeedStack7™ different from regular lens covers?

Most current lens covers are single-layer pieces of film mounted using 2 strips of double-sided tape. SpeedStack7™ tear offs come prelaminated, optically indexed providing 7 individual layers vs just 1 layer and they use a full perimeter adhesive system offering protection against liquid and debris from getting behind the tear off.

Are SpeedStack7™ layers optically clear?

Yes. Every layer of SpeedStack7™ is optically indexed and distortion-free, maintaining crystal-clear visibility through all 7 layers. With 85% visible light transmission through all 7 layers combined, you'll experience the same high-quality vision on layer 7 as you did on layer 1.

Can I get samples to try before buying?

Sample packs are not currently available. We recommend purchasing a standard pack to evaluate SpeedStack7™ performance in your specific application. For special evaluation requests, please contact info@industrialdefense.com.

Installation & Usage

How do I install the lens protector?

Preparation:

1. Clean your lens thoroughly with mild soap and water

2. Dry completely with a lint-free cloth

3. Ensure the surface is free from dust, oil, and fingerprints

Application:

1. Remove one 7-layer stack from packaging

2. Align the protector with your lens edges

3. Press one edge to the lens and smooth across using a squeegee motion

4. Work from center outward to eliminate air bubbles

5. Apply firm, even pressure across the entire surface

How do I remove a soiled layer during work?

1. Locate the tear-off tab at the edge of the top layer

2. Grip the tab firmly with your thumb and index finger

3. Pull quickly and smoothly in one continuous motion

4. The soiled layer peels off completely, revealing a fresh layer underneath

5. Continue working immediately—no downtime required

Does SpeedStack7™ leave any residue when removed?

No. SpeedStack7™ is designed for clean, residue-free removal. When you tear off a layer or remove the entire stack, your lens remains clean with no adhesive left behind.

Does SpeedStack7™ leave any residue when removed?

No. SpeedStack7™ is designed for clean, residue-free removal. When you tear off a layer or remove the entire stack, your lens remains clean with no adhesive left behind.

How long does each layer last?

Each layer lasts until obstructed.

How should I store unused SpeedStack7™ stacks?

Store in a cool, dry place for up to 18 months.

What temperature range does SpeedStack7™ work in?

SpeedStack7™ is engineered for all-conditions performance, with an operating temperature range of -30°C (-22°F) to 120°C (248°F). This wide range ensures reliable adhesion and optical clarity in both extreme cold and high-heat industrial applications, making it suitable for indoor and outdoor use year-round.

Performance & Durability

Is SpeedStack7™ scratch-resistant?

Yes. SpeedStack7™ protects your polycarbonate or glass lens with a physical barrier. The top layer features a scratch-resistant, hard-coated surface designed to withstand industrial environments and abrasive particles.

Will this affect my visibility or optical clarity?

No. SpeedStack7™ maintains 85% visible light transmission through all 7 layers, ensuring clear vision while you work.

Can these withstand high temperatures?

Yes. SpeedStack7™ operates reliably in temperatures ranging from -30°C (-22°F) to 120°C (248°F).

Are they chemical resistant?

SpeedStack7™ lens protectors are made from optical grade polyester (PET), which offers good chemical resistance for most industrial applications. The material resists weak acids and bases, alcohols, oils, greases, and many common industrial solvents. However, prolonged exposure to strong acids, strong bases, or certain organic solvents (like acetone or MEK) may affect the material. For harsh chemical environments, we recommend more frequent layer changes to maintain optimal protection. If you work with specific chemicals and have concerns, contact us at info@industrialdefense.com for guidance.

Will they perform in extreme cold or heat?

Yes - SpeedStack7™ operates reliably in temperatures ranging from -30°C (-22°F) to 120°C (248°F).

Will they fog up?

SpeedStack7™ does not prevent fogging, as fog is caused by temperature, humidity, and ventilation factors in your respirator or work environment. However, our optical grade polyester material does not add any fog risk or distortion.

Technical Specifications

What is SpeedStack7™ made of?

SpeedStack7™ is manufactured from optical grade polyester, chosen for its exceptional clarity, durability, and consistent performance in demanding industrial environments.

What type of adhesive does SpeedStack7™ use?

SpeedStack7™ uses an optically clear, pressure-sensitive, acrylic adhesive. This full-perimeter adhesive system provides superior protection against liquid and debris infiltration while ensuring clean, residue-free removal.

Does SpeedStack7™ have anti-static properties?

Yes. SpeedStack7™ incorporates anti-static technology to prevent static buildup that attracts dust and debris, keeping your lens cleaner longer.

What is the light transmission rating?

SpeedStack7™ provides 85% visible light transmission through all 7 layers combined, ensuring excellent visibility throughout the entire product lifespan.

How thick is each layer?

Each individual layer is 2 mil (2 thousandths of an inch, 0.002", 0.0508 mm). The total stack thickness for all 7 layers combined is 14 mil (14 thousandths of an inch, 0.014", 0.3556 mm).

Does SpeedStack7™ affect my equipment's safety rating?

SpeedStack7™ is designed as an accessory protective layer and does not modify the function or safety rating of your underlying PPE equipment. Always ensure your primary safety equipment meets all required OSHA and workplace safety standards.

How do I dispose of used SpeedStack7™ layers?

Dispose in trash. If layers are contaminated with hazardous materials from your work environment, treat as contaminated waste per applicable regulations.

Is SpeedStack7™ patented?

Yes. SpeedStack7™ technology is protected by U.S. Patents: 6,388,813, 6,536,045, and 6,847,492.

Value & Comparisons

How does SpeedStack7™ compare to replacing entire lenses?

Applying the SpeedStack7™ tearoffs is very easy and quick when compared to the time and effort of removing a costly helmet or respirator lens and then installing a replacement.

What's the cost savings versus buying new lenses?

New lenses can range anywhere from $10 to $200 depending on make, model and manufacturer which is well over the cost of a single 7 layer tear off.

How does SpeedStack7™ compare to disposable face shields?

Disposable face shields (designed for 1 use, then thrown away) typically cost $3.00 USD, so to get 7 usages the cost would be $21.00 USD. Besides the waste of going through 7 disposables, the cost of a single SpeedStack7™ tearoff is lower when compared on a per-layer basis, to say nothing of the time to find and replace the disposable.

How does SpeedStack7™ help with productivity?

SpeedStack7™ eliminates downtime caused by lens cleaning or equipment removal. When your lens gets dirty, simply tear off the top layer and continue working—you're back to work in seconds, not minutes. Over a full shift or workweek, this adds up to significant time savings.

Does SpeedStack7™ help extend the life of my equipment lenses?

Yes. SpeedStack7™ protects your polycarbonate or glass lens with a physical barrier against scratches, abrasion, and debris impact. This helps preserve your expensive equipment lenses and reduces replacement frequency.
